A-dec · Dental Equipment · $8,000 – $18,000
Chairs under 8,000 hours with no service gaps in the last 2 years hit $15K–$18K fast. One missing maintenance record or visible yellowing on the upholstery tanks you $2,000–$3,000 instantly because clinic managers won't inherit unknown problems.
Pop the backrest control panel and look for hydraulic fluid seepage - any discoloration means the cylinders are on borrowed time. Run the delivery system handpiece under water for 30 seconds and listen for cavitation noise (grinding sound); if you hear it, budget $1,500–$2,200 for seal replacement. Take photos of the LED light refractor; if it's got cracks or dust under the lens, that's a $400 fix.
California DSOs (especially Los Angeles and Orange County) snap up A-dec 500s in the $12K–$15K range because used equipment is faster to deploy than waiting 16 weeks for new. Texas markets (Dallas, Houston) are softer; you'll move chairs faster at $9K–$11K because smaller practices buy there and want cash-on-hand.

Over 12,000 hours you're in replacement territory for seals, bearings, and the backrest cylinder. Most Heartland Dental locations cycle chairs out around 10,000–11,000 hours. Go above 14,000 and you're basically buying a parts donor.
Upholstery kills more because it's cosmetic and visible in a walkthrough. But mechanics kill the *good* deals. A torn cushion costs $600 to reupholster; a leaking hydraulic pump costs $2,800 and kills buyer confidence entirely.
Bundle it. Separating them looks like you're nickel-and-diming. Sage Dental won't even look at a chair listing that breaks out the light as add-on; they assume you're hiding something.

I saved a buyer in Irvine 8 weeks of downtime by catching a delivery system leak before closing - would've cost them $3,000 in emergency service calls. Proper documentation cuts negotiation time from 3 weeks to 5 days, meaning your cash closes faster.
